FILTER-FAUCET.

SPECIFICATION forming part of Letters Patent No. 701,943, dated June 10, 1902.

Applicationv filed June 26, 1 901.

To all whom it may conccrmf Be it known that we, J OHN F RYAN, residing at Brooklyn, and WILLIAM MOEWAN,

residingat Winfield, State of Ne'wJYork,

citizens of the United States, have inventedcertain new and useful Improvementsiin Compression Filter-Faucets with Automatic Cleaners, of which the following is a specification. 7

Our invention relates to compression filter-- horizontal section through the filter on the line 2 2 of Fig. I, and Fig. III is a rear view of the automatic cleaner. 7

The principal object of our invention is to produce a filter-faucet which will deliver either filtered or unfiltered water in a regulable quantity. The advantages of such a structure are many, the principal of which is that when the faucet is adapted to deliver either filtered or unfiltered water but a'single fixture is necessary, and, being at a constant normal height, the pail or other receptacle may readily be placed beneath it, whereasif the filter be made removable and be not adapted for delivering unfiltered water it would, be

necessaryto change the-position of the faucet in order to accommodate the filter to the pail or other receptacle placed in the sink.

- A further object of our invention is toproduce a filter-faucet which may be readily sub-.

stituted for theordinary faucets now inuse, so that no change in piping will-be necessary or desirable. r

In thedrawings, a represents a suitable filtor-casing provided with a thread 1, suitable for connecting the same with any desired service-pipe. The faucet shown in the drawings is adapted to be secured to a sink; but if it be desired-to attach the faucet to a basin the inlet-pipe may be constructed as shown in the dotted line. The faucet is provided at 2 with a left thread adapted to receive a threaded spindle and at 3 with a thread, over Which a bonnet 4 is adapted to fit. The cas- "ing the parts together. I the outside ofthe casiugandis provided with a nipple 8,;adapte'dito receive -a thimble 9.

valve faces or packing, ashereinafter described. The bonnet l is bored to receive a sure of the Water.

ing isprovided at 5 with a thread to receive a cap 6 and with a hon-circular portion, preferably a-hexagon, adapted to be engaged by a wrench or spanner for the purpose ofscrew- The cap 6 engages on The cap 6 isiprovidedwith-an upper seat 10 and a lower seat 11 to cooperate with suitable stem ,12,"provided with a handle 13 for rotatingthe-sarne. The ste1n'12 carries a threadedspindle 1.4, provided with a left thread to engagein thethread 2 of the casing a. The

spindle 14: carries two heads or flanges 15 16,

between which is carried a filtering element 117, preferably a cylinder of kieselguhr or stone. The spindle 14 is provided with wings 18, forming between them ducts or channels, which lead to passages 19 in a solidportion of 'the spindle 14. These passages lead to lateral apertures 21 in aferr ule 20, from which ble 9. The lower endof the spindle isprovided witha washer 22, adaptedto cooperate with the valve-seat 10, and with a washer 23,

the. wateris delivered laterally into the thimadaptedto-cooperatezwith the valve-seat 11.

"These washers are spaced apart by the ferrule 20, and the'washers 'andQferrule are held in placeby a 111111124,- screw threaded on the lower end of the seamen and provided with a lateralflange 25:...

I The device is provided with a scraper er cleaner. 7 This scraper or cleaner is shown in the drawings as'a scraper blade or blades 26,

carried by a stem 27, which stem enters thev inlet-aperture 28 of the faucet. The scraper is held firmly against the stone by the pres Heretofore it has been customary to employ spring-pressure to force the scrapers or cleaners against. the sides 'of 1 the stone. It has been. found, however, in.

practice that owing to the"wearing awa of the stone and from other causes thespringactuated scrapers are not commercially successful in use. This difficulty, however, is obviated by our invention, as the water-pressure may be utilized regardless of the size of the stone;

The operation of the structure is as follows: Water entering at 28 will force the cleaner or scraper-blade 26 firmly against the stone and will pass through the cylindrical stone into the passage into the interior thereof and will pass through the ducts 19 and the passages 21 of the ferrule into the thimble 9 and thence out of the filter. The water will thus be filtered. This will occur when the filter is in position shown in the drawings. When it is desired to deliver unfiltered water, the handle 13 may be rotated, thereby rotating the spindle and raising the stone and other parts carried by the spindle and lifting the washer 22 clear of the valve-seat 10 and bringing the washer 23 firmly into contact with the valve-seat 11. The water will now flow freely around the stone, out through the lower end of the spindle 1i, without passing through-the stone.

It will he understood that in this specification we have used the term washer to designate the portion of the structure indicated in the drawings by the numerals 22 and 23. It will be understood, however, that in using the term washers we mean to include therein any other form of constructionsuch as a flange, f0rinstancewhich within the limitations imposed by the state of the art are the equivalents of washers.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s

1. In a filtering-faucet, the combination of a filtering medium, a rotary spindle and a plurality of valves or washers carried by the rotary spindle and arranged on opposite sides of an annular diaphragm provided with valveseats on opposite sides thereof.

2. In a filtering-faucet, the combination of inlet and delivery ports, a filtering medium and a spindle carrying the said filtering medium and provided with a plurality of washers and valve-seats intervening between the washers.

3. In a filtering-faucet, the combination of a cylindrical filtering medium, a winged spindle passing therethrough and provided with apertures for the passage of water from the interior of the filtering medium.

4. In a filter the combination of a spindle provided with a plurality of washers, valveseats intervening between the washers and a ferrule adapted to space the said washers apart.

5. 'In a filter the combination of a filtering medium, a spindle carrying the said filtering medium, a plurality of washers carried by the spindle and valve-seats intervening between the said washers.

6. In a filter the combination of a filtering medium, a plurality of valve-seats and a plurality of washers, the said valveseats intervening between said washers and a ferrule also intervening between the said washers.

7. In a filter-faucet the combination of a hollow filtering medium, a spindle carrying the said filtering medium, a plurality of wash ers or valves carried by the said spindle, valve seats intervening between the said washers and openings adapted to accommodate the fiow of water, irrespective of the position of the washers with respect to their valve-seats.
